A irther object is to provide awater heater having air conducting pipes extend mg from the opposite ends of the heaterto the atmosphere so as'to maintain afcontinuous current of airlthroughthe heater and thus carry off the gas escaping at the burner tip.- I

It will thus be seen that by means of the pipes 2. and 27 a, continuous circulation of air is maintained within. the casing so that should thegas be accidentally left turned on the gas escaping at the burner tip will be taken up by the current of air entering through the pipe 23 and carried oii through the pipe 27 thus preventing the gas from entering the room and asphyxiating the occupants of the building.

While the arrangement for removing the signed escapiiifg' gas from the room is principally deor use in connection with hot Water heaters it is obvious that the same may be used with equally good results on gas stoves used for cooking or heating purposes or wherever a device of; this character isfound desirable.
